How can I create an X-Y plot in Signal Express?

Primary Software: LabVIEW Signal Express>>Development System
Primary Software Version: 2.0
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem: I am using Signal Express to record signal data from two channels.  I want to plot the data obtained from Channel 1 vs. Channel 0 instead of plotting Channel 1 vs. time and Channel 0  vs. time.

Solution:
  1. Open Signal Express

  2. Click on "Add Step" to setup data acquisition (very similar to tasks in DAQmx) and configure your task



  3. Click on the blue plus sign to add acquisition from another channel to this step.  ***You can also add another step to compare signal from another card.



  4. Click on record and select all of the channels you wish to record.  Your screen should show the signals of that step



  5. Click on the “Data View” tab to bring up the graph



  6. In the left window is a list of the steps.  Click on the plus sign to expand the step to see the list of channels associated with a certain step.  Click and drag the two channels to the black graph in the middle pane.  They both should show up on the graph.  ***You can add channels from different steps.



  7. Right click on the graph and go to View As -> XY Graph



  8. If you want Channel 1 vs. Channel 0 INSTEAD of Channel 0 vs. Channel 1, you right click on the graph and go to plot order
